In order to be able to Further configure my system, I am looking for a fork of my current OS (artix with openRC as init system) in which i am able to compile every package from source in order to Further configure it with make flags. I am currently not using gentoo, and because the packages in its default repos are only updated when necessary, and the break-my-gentoo repo is more of a joke than an actual replacement for arch. However, if someone can recommand me a repo with similar package updates as arch, I would be looking at installing gentoo.
If you are looking for a distro similar to Arch where you can compile everything from source you can just use Arch. https://wiki.archlinux.org/title/Arch_build_system
Disclaimer: I have never used this feature so don’t know how easy it is to use, but I do use Arch which is how I know it exists. (I use Arch btw)
